Bosch Dishwasher Error Code d:01

The d:01 code on a Bosch dishwasher means the motor control unit has detected an internal short circuit. This fault shuts down the dishwasher to prevent further electrical damage. The motor control is the module that regulates the circulation pump motor, and it must be tested and replaced to resolve the error.

No, you should not attempt to run the dishwasher while d:01 is active. A short circuit in the motor control can pose an electrical hazard and may cause further damage to other components. Keep the dishwasher powered off until the fault is diagnosed and repaired.

Repair costs for d:01 typically depend on the cost of the motor control module and labor. Parts alone can range from roughly $80 to $250 depending on the specific model, and professional labor charges can add $100 to $200 or more. If the circulation pump motor has also failed and needs replacement, total repair costs will be higher.

Diagnosing d:01 requires running test program P:04 to confirm the motor control has failed. If you are comfortable working with appliance electronics and disconnecting power safely, the motor control module can be replaced as a DIY repair. However, because this involves a short circuit condition, many technicians recommend having a professional handle the replacement to ensure correct installation and to rule out underlying issues with the pump motor or wiring.

A simple reset will not clear d:01 because the fault is caused by a physical short circuit in the motor control hardware, not a software glitch. The error will return immediately or the dishwasher will fail to operate normally until the faulty motor control unit is replaced. Test P:04 should be run to confirm the fault before any parts are ordered.
